Hydrogen-fueled 18-wheeler emits only water from tailpipe

Toyota delivered a zero-emissions 670-horsepower truck to the ports of Los Angeles and Long Beach on Wednesday that could ultimately reverse the region’s high cancer-causing pollution levels. If the hydrogen-powered big rig performs well during a summer-long pilot test dubbed “Project Portal,” the new heavy-duty carrier could be the model to replace thousands of diesel trucks that pass to and from the twin ports daily.
